Application led December 1'3, 1924, Serial Rol 755,661. Renewed February18, 192'?.y

This invention relates to storage batteries for automobiles to reduce`corrosion ofthe storage batter terminals. y

Further obJects and advantages of the 5 present invention will beapparent from the following description, reference being had to theaccompanying drawings, wherein a nected with their respective positiveand f negative connector bars 22 and 23 provided,

.20 respectively, with terminal posts 2,4 and 25.

The jar is provided with a cover 26 which is apertured to receive theterminal posts 24 and 25, and isl provided 'with a threaded opening 27for receiving a plug 28 -which is removed when filling the battery cell.The

upper endsof posts 24 and 25 are tapered in order to receive terminalclamps 29.

It has been found that corrosion frequently takes place between theterminal clamp and thebattery post due to acid working its way u wardlyfrom the battery or the spilling o acid' upon the battery cell cover.

Generally 's corrosion takes fplace in a Fig. 1 of the drawings is asectional view region of the post and clamp represented by the closelyspaced cross-hatch lines 24* and 29 in Fig. 1, and is concealed when theclamp is placed firmly post. A

This corrosion is Substantially eliminated by the use of a ring 30 offelt or other fibrous absorbent material which is preferably soaked withvaseline or other acid-resisting grease or compound placed betweenthe'battery cell cover and the' clamp. The presence of theacid-resisting material tends to prevent the acid'from creeping up abovethe felt washer upon the surfaces of contact of the clamp and terminalposts. The fibrousmaterxal should be made of acid-resisting libres, suchas woolen fibres.

While theform of embodiment of the .invention as herein disclosed,vconstitutes a preferred form, it is to be understood that other formsmight be adopted, all coming within the scope of the claim whichfollows.

What is claimed is as follows:

The combination with a storage battery upon the terminal lhaving acover, a terminal post extending exteriorly of the cover, a terminalclamp u on the post,'o f a washer of acid-resisting fibrous material imregnated with acid-rex sisting grease locate between the clamp and coverand surrounding the post.

In testimony whereof hereto ax my i signature. y
